Use a gadget with a lithium-ion battery inside and you'll eventually learn that these power packs decay once you've cycled them enough times. But have you ever wanted to see direct evidence of why they have a limited lifespan? The Department of Energy is happy to oblige. It developed a special dev...

The deep frying process isn't just useful for livening up your food -- it might also be the ticket to better batteries in your mobile devices. South Korean researchers have created highly conductive, stable electrode materials by spraying graphene oxide droplets into a very hot blend of acid and o...

One of the last times we saw the concept of a self-recharging battery, it was part of a high-minded Nokia patent whose ideas still haven't seen the light of day. Researchers at Georgia Tech are more inclined to put theory into practice. Starting from a regular lithium-ion coin battery, the team ha...

So Apple could be working on an iPhone with a thinner display, you say. Look what we have here, possibly in the nick of time: it's a newly granted Apple patent for a screen with in-cell touch, where the LCD and touch recognition are integrated into one panel instead of stacking up in separate laye...

Touchscreens can't differentiate between you, your friend or your cat. Truth is, they're actually amazingly simple pieces of technology without much in the way of brains. A new type of display shown off at the International Nanotechnology Exhibition & Conference in Tokyo last week does imbue th...

Graphene, that microscopic chicken wire made of carbon atoms, has a great many theoretical uses. Among these is to improve Lithium-ion battery technologies, and the big brains at the Lawrence Berkeley National Laboratory have created a graphene and tin composite material for use in battery electr...

Add that magical material known as graphene to the list of things you can make with inkjet printers alongside OLEDs, solar panels, and light-bending metamaterials. Scientists at the Seoul National University used printers and a technique known as vapor deposition to leave a thin film of the graph...

Researchers at MIT reckon they've struck oil. In fact, you're looking at what they call "Cambridge crude" -- a substance that could halve the weight and cost of EV batteries and make them quicker to charge too. The black goo is packed with a high concentration of energy in the form of particles s...

Here's an amazing story to end your week on a high note: a 25-year-old paraplegic is now walking again, thanks to a groundbreaking procedure developed by neuroscientists at the University of Louisville, UCLA and Cal Tech. The Oregon man, Rob Summers, was paralyzed below the chest in 2006, after gett...

As trippy as mind-control still seems to us, we've already seen it implemented in everything from wheelchairs to pricey gaming (and car driving!) headsets. But the problem is that they measure brain activity outside the skull -- you know, the thing we've evolved to shield the murky goings-on in our...

Need further confirmation that an IV drip of 5-Hour Energy is what your body really needs? Look no further than Murata's newfangled fatigue sensor. Demonstrated at CEATEC in front of thousands of jetlagged Americans, Europeans, Easter Islanders and Samoans, this compact device is built by "integrati...

Looking to spark up a makeshift psychology lab in the basement of your house? Look no further than the galvanic skin response computer mouse. For those unaware, GSR electrodes can gather data about human interactions with computers, though most rigs are so invasive that test subjects end up freaki...

Scientists in eastern China have successfully experimented with brain-motor skill manipulation in pigeons to "force the bird to comply with their commands." Micro electrodes have been planted into the brains of these pigeons to control their movement left, right, up, and down during flight. While ch...

It's fairly reassuring that if those rollable, water-powered, paper, and ultracapacitor-based battery ideas don't exactly pan out, we've got yet another idea coming out of MIT that just might gain traction. Apparently, scientists at the university are working on self-assembling Li-ion cells when not...

We've seen hybrid batteries, hairy capacitors, and ultracapacitors, but considering how much we depend on batteries, we're not ones to turn up our noses at yet another new battery development. This latest one comes from researchers in France, who have turned to nanotechnology to create lithium-ion b...
